How to Take Care of a Rat as a Pet

Introduction

Pet rats are among the most intelligent, affectionate, and interactive small pets you can own. They're often called "dogs in a small package" — they learn their names, come when called, can be trained to do tricks, and genuinely enjoy human companionship. Here's a complete guide on how to take care of a rat as a pet.

Rats Are Social — Always Keep in Groups

Rats are highly social animals that should never be kept alone. A solitary rat will be lonely, stressed, and prone to depression and illness. Always keep rats in same-sex groups of at least two, ideally three or more. Two males (bucks) or two females (does) are the most common pairings; females tend to be more active and playful, males tend to be calmer and more cuddly.

Housing

Rats need a large, multi-level cage with solid or closely-spaced bar flooring. The Large 4-Tier Ferret/Rat Rolling Cage is an excellent choice — it provides generous vertical space with multiple platforms, tight 1/2-inch bar spacing to prevent escape, front doors on each level, and rolling wheels for easy repositioning. Minimum cage size for two rats is 2x2x3 feet; bigger is always better.

Bedding

Line the cage base with 1–2 inches of Oxbow Pure Comfort Bedding — 99.9% dust-free and highly absorbent. Rats are prone to respiratory problems, so dust-free bedding is especially important. Avoid cedar and pine shavings. Provide nesting material (torn paper towels or tissue) for rats to build nests.

Diet

Rats are omnivores with varied nutritional needs:

• Quality rat block/pellet — A lab block-style pellet (such as Oxbow Essentials Rat Food) should form the dietary base; feed ad libitum (always available)
• Fresh vegetables — Offer a variety of fresh vegetables daily: broccoli, peas, carrot, leafy greens, cucumber
• Occasional protein — Cooked chicken, scrambled egg, or mealworms 2–3 times per week
• Treats — Oxbow Organic Rewards Biscuits for training and bonding
• Fresh water — Via no-drip water bottle, changed daily

Exercise and Enrichment

Rats need at least 1–2 hours of supervised free-roaming time outside their cage daily. They're intelligent animals that need mental stimulation — provide hammocks, tunnels, ropes, and foraging toys inside the cage. Use a portable playpen for safe floor time. Rats can be trained to navigate obstacle courses, retrieve objects, and respond to their names.

Handling and Bonding

Rats tame quickly and most become very comfortable with handling within days to weeks. Handle daily from a young age, offer treats from your hand, and let them explore on your shoulders and lap. Rats that are handled regularly from a young age become extremely affectionate companions.

Health Basics

Rats are prone to respiratory infections (mycoplasmosis), mammary tumors (especially females), and hind leg degeneration in old age. Find an exotic animal vet experienced with rats before you need one. Keep a pet thermometer and oral syringes on hand.

Lifespan

Pet rats typically live 2–3 years. Their short lifespan is one of the most emotionally challenging aspects of rat ownership, but the depth of bond formed in those years is remarkable.

Conclusion

Pet rats are extraordinary companions — intelligent, affectionate, and endlessly entertaining. They require social housing, a spacious cage, a varied diet, and daily interaction. Give them what they need and you'll have some of the most rewarding small pets you've ever owned.
